ery thereof and is held confined between the Adapted to flow into the casing I0, preferably to a level as at 29, is a quantity of water 30, the depth thereof being such when within the body i Illto wet the ltering material 28 on the rotation vof the `cylinder 24. The axle 23 of this cylinder has fixed thereto a belt wheel 3|, having trained thereover an endless belt 32, which is also trained over a belt pulley 33. 'I'his pulley 33 is fixed to a driven shaft 34 carrying a belt wheel 35 over which is trained an endless belt 3'6. The belt 36 is `trained over a pulley 31 xedto the power shaft I9 of the electric motor and the latter furnishes the powerv for the rotation of the cylinder 24. The arrangementrof the belt pulleys, belts and belt wheels between the motor I8 andv the cylinder i 24 regulates the speed of rotation 'of the rsaid cylinder. y

`Arranged within the casing l0' elevated with respect to the lcylinder 24 is a'water supply tank Shaving a delivery porty controlled by a valve 39, v`its stem 40 being pivoted, at 4I to the rocker arm 42 .fora ball float 43. The arm 42 'is swingingly carried by a bracket 44 secured to one side wall'of the casing Ia determined distance above the bottom ofthe said casingV I0 so that the oat 43 will be affected by the quantity of Water 3,0

within'the casing '10. On the. lowering of the quantity of water 30 vin `the lower 'portion of the casing I0, the valve 39 becomes operated by the ,float 43 and on openingof such valve'thewater VYwithin the'tank 38 will drop through gravity to thehottom of the casing luy forfthe bringing lof thei-antity of water to a determinedlevel with- .iriisaid casing resulting inthe closing of the valve *39"to shut oi further-water supply from the tank 38. A'Iheair Within a room is caused to'belcirculated for the operation of the fan wheel.

In theoperation' of the apparatus, the air within an enclosure'is admittedfthrough the intake opening l3 at therear ofthe casing, I0 4to the interiorro'f 'the-latter' and by the action ofthe Vlfan wheel'20 this air y Willbedrawn'throughthev filtering medium 28when' circulating en rterlorly about the cylinder 24 when: rotatingand. such air.V becomes filtered when drawn ,within the cylinder whence the fan wheel-discharges the air fromsaid cylinderthrough thelfront 4opening: l2

The tank 3s is enea with@ quantity of water on removing the cover I2 from the casing l0'.

the enclosure after beingtaken ktherefrom into cylinder beingclosed the water 30 within the lowered portion of the casing I0 moistens or wets the filtering medium 23 peripherally about the cylinder 24 and in this way dust or other foreign matter will' be collected by said filtering medium for the removal thereof from the air when passing through ,the appal ratus and air conditioned thereby.

The/cylinder 24 extends a distance in close re- I elation .to the front and rear walls of the casing I0 and the front openend of this cylinder incasesthe motor. the belts, the belt Wheels and pulleys under the ,arrangement .thereof as herelnbefore set forth.

'I'he quantity. of water within the lower portion ofthe casing I0 is maintained at a determined level through theoperation of the oat 43 and the valve 39 controlled thereby.
